The poster presents the main achievements of the capacity building project ALCOREF “Forensic alcohol reference materials”. The project was part of the European Metrology Programme for Innovation and Research (EMPIR).
Altogether 43 certified ethanol in water reference materials (CRMs) in the mass fraction range of 0.1 to 7 mg/g were developed by project partners. These CRMS are suitable for the calibration and verification of evidential breath alcohol analysers according to the requirements of the International Organisation of Legal Metrology (OIML). Furthermore, 10 new or improved Calibration and Measurement Capability (CMC) claims for purity assessment of ethanol and ethanol quantification were prepared. Newly established measurement capabilities and the new CRMs were successfully tested in three intercomparisons conducted as official intercomparisons of EURAMET Technical Committee for Metrology in Chemistry.
